PATENT- OFFICE MICHIGAN, ASSIGNOR T KEELEB BRASS COMPANY, OF GRAND RAPIDS, MICHIGAN KNOB FOR FURNITURE Application filed July 18,

Fig. 1 is a side view of my improved knob. I

Fig. 2 is a central section on line 22 of Figs. 1 and 3.

Fig. 3 is an inverted view. 7

My improved knob, in the embodiment illustrated, comprises an outwardly tapered shank l formed of sheet metal, the outer end of the shank being turned inwardly upon itself, the inturned portion 2 forming an internal shoulder this inward turning of the end of the shank providing a round finished edge 3.

The back plate 4 of general concavo convex form is formed of sheet metal with a central tubular stud 5 disposed within the inturned portion 2 of the shank and secured therein by fianging or upsetting the end 6 of the stud upon the shoulder formed by the inturned portion 2. This stud is internally threaded at 7 to receive the attaching screW.

The face plate 8 also formed as a sheet metal stamping is of concavo convex form, its periphery 9 being flanged or turned over the edge of the back plate. The periphery of the back plate is outwardly oifset providing a shoulder 10 against which the inturned edge of the face plate abuts, thereby forming a smooth joint. 7

With the parts thus arranged, I am able to produce the knobs very economically and of attractice design with no exposed rough edges.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

In a knob for furniture and the like, the combination of a shank having its outer end 1929. Serial No. 379,169.

turned inwardly upon itself providing an internal shoulder, and a head provided with a central stud fitting within said inturned portion of said shank and upset upon the inner edge thereof whereby the head and shank are secured together. I

In witness whereof I have hereunto set my hand.

ALBERT L. BIRDSALL.
